You can keep your plants well-watered by arranging for Twitter alerts when they're thirsty, but using a wine bottle as a "plant nanny" to maintain consistent levels of moisture seems more efficient. Plus you can sate your own thirst, too.
The Early Show has a neat way of saving money by using empty wine bottles instead of store-bought "plant nannies." It's as simple as filling up the wine bottle with water, putting a spike on the end, and sticking the entire contraption upside down into a planter. Water will seep into the dirt gradually and keep your plants sated without drowning them.
It's a great, simple solution for keeping your plants watered without much work on your part. Have your own neat use for empty wine bottles? Or do you have a particularly sneaky way of making your plants not even notice that you're gone? Tell us all about your tricks in the comments.
